Give reason :
`SC^(3+)` ions are colourless whereas `V^(3+)` ions are coloured.

Text Solution

`Sc^(3+)` ions are colourless, whereas `V^(3+)` ions are coloured because, `V^(3+)` ions contains partially filled d-orbitals. Therefore they have d-d transition of electrons, which results in imparting color to the ions.
